Elastic connecting support

1. An elastic connecting support for arrangement between a combustion engine and an air filter of a handheld work apparatus, the elastic connecting support comprising:

a first channel for largely fuel-free air;

a second channel fora fuel/air mixture;

the elastic connecting support being realized as a single piece and having a first side and a second side;

an engine connecting flange disposed at said first side for connection to the combustion engine;

said first channel and said second channel ending at said engine connecting flange;

said first channel having a first peripheral wall;

said second channel having a second peripheral wall;

said first peripheral wall and said second peripheral wall being arranged at a distance (v, h 2 ) in relation to each other in a longitudinal section of the elastic connecting support;

said first channel and said second channel extending from said first side to said second side of the elastic connecting support;

a common connecting flange disposed at said second side;

said first channel and said second channel ending at said common connecting flange; and,

wherein a through opening is defined between said first peripheral wall and said second peripheral wall in said longitudinal section.

2. The elastic connecting support of claim 1 , wherein said longitudinal section extends as far as said engine connecting flange.

3. The elastic connecting support of claim 1 , wherein said first channel has an expansion fold running in a peripheral direction of said first channel.

4. An elastic connecting support for arrangement between a combustion engine and an air filter of a handheld work apparatus, the elastic connecting support comprising:

a first channel for largely fuel-free air;

a second channel fora fuel/air mixture;

the elastic connecting support being realized as a single piece and having a first side and a second side;

an engine connecting flange disposed at said first side for connection to the combustion engine;

said first channel and said second channel ending at said engine connecting flange;

said first channel having a first peripheral wall;

said second channel having a second peripheral wall;

said first peripheral wall and said second peripheral wall being arranged at a distance (v, h 2 ) in relation to each other in a longitudinal section of the elastic connecting support;

said first channel and said second channel extending from said first side to said second side of the elastic connecting support;

a common connecting flange disposed at said second side;

said first channel and said second channel ending at said common connecting flange; and,

said first channel having an expansion fold running in a peripheral direction of said first channel; and,

wherein only said first channel has said expansion fold running in the peripheral direction.

5. The elastic connecting support of claim 3 , wherein said expansion fold is arranged in said longitudinal section.

6. The elastic connecting support of claim 3 , wherein:

said engine connecting flange has a connecting surface and a height (h 1 ); and,

said distance (v) between said first peripheral wall and said second peripheral wall measured in a direction parallel to said connecting surface of said engine connecting flange, starting from a middle of said expansion fold is at least 5% of said height (h 1 ).

7. The elastic connecting support of claim 3 , wherein:

said first channel has a first wall thickness (w 1 ) in a first region of said expansion fold;

said first channel has a second wall thickness (w 2 ) in a second region adjacent to said expansion fold; and,

said first wall thickness (w 1 ) is less than said second wall thickness (w 2 ).

8. The elastic connecting support of claim 3 , wherein said expansion fold is arranged closer to said first side than to said second side.

9. The elastic connecting support of claim 3 , wherein said expansion fold extends fully around said first channel.

10. The elastic connecting support of claim 3 , wherein:

a through opening is defined between said first peripheral wall and said second peripheral wall in said longitudinal section; and,

said expansion fold projects into said through opening.

11. The elastic connecting support of claim 3 , wherein:

said second channel has a third region and a fourth region;

said third region has a third wall thickness (w 3 );

said fourth region has a fourth wall thickness (w 4 ); and,

said third wall thickness (w 3 ) is less than said fourth wall thickness (w 4 ).

12. The elastic connecting support of claim 11 , wherein said third region of said second channel is arranged in said longitudinal section.

13. The elastic connecting support of claim 11 , wherein said third region is arranged closer to said first side than to said second side.

14. A handheld work apparatus comprising:

a combustion engine;

a carburetor;

an elastic connecting support having a first channel for largely fuel-free air and a second channel for a fuel/air mixture;

said elastic connecting support being realized as a single piece and having a first side and a second side;

said elastic connecting support having an engine connecting flange disposed at said first side for connection to the combustion engine; said first channel and said second channel ending at said engine connecting flange;

said first channel having a first peripheral wall;

said second channel having a second peripheral wall;

said first peripheral wall and said second peripheral wall being arranged at a distance (v, h 2 ) in relation to each other in a longitudinal section of the elastic connecting support; said first channel and said second channel extending from said first side to said second side of the elastic connecting support;

said elastic connecting support having a common connecting flange disposed at said second side;

said first channel and said second channel ending at said common connecting flange;

said elastic connecting support being arranged between said combustion engine and said carburetor; and

wherein a through opening is defined between said first peripheral wall and said second peripheral wall in said longitudinal section.
